Question

What do transformers do in the generation and distribution of electrical energy? Check all that apply.
decrease voltage
convert water into steam
increase voltage
turn turbines
turn generators

Answer 1

Answer:

1. Decrease Voltage

2. Increase Voltage (In Step-Up transformers)

Explanation:

Transformers usually deal with the roundabouts of electricity, though, they can be also used in generators to transfer energy, they are also made to manage the flow by increasing or decreasing it. Converting water into steam is usally done by a boiler (Such as the core in a thermonuclear reactor (Boiling Water Reactor)), turning turbines and generators are usually done by mechanical energy, such as the steam flowing through the turbine, or water flowing through the generator/turbine in a hydroelectric power plant.

Answer 2

decrease voltage in step-down transformers

increase voltage in step-up transformers

Explain Transmission of Electrical Power.

• Transformers are broadly used in the electric power industry to increase voltages—known as step-up transformers—before long-distance transmission via high-voltage wires.
• they're also used to decrease voltages—known as step-down transformers—to deliver electricity to homes and businesses.
• the overwhelming majority of electric power is generated by the usage of magnetic induction.
• Hydroelectric power plants use the kinetic energy of water to drive electric turbines.
• Coal or nuclear power plants create steam to drive steam generators that turn the coils.

once power is generated, the power must be transmitted to the consumer, this means transmitting this power for hundreds of km. To do this, the voltage of the power plant is increased by using a step-up transformer, this is stepped up, and the current decreases proportionally because
